Progress ABL - What does "?" mean in a method argument?

In my current project, I'm converting some Progress code to C#. One of the statement to convert is: 

RUN GetNewJobAsmblMultiple IN hIssueReturn(tranType,"?",callProcess,{&input_dataset_SelectedJobAsmblDataSet}, OUTPUT pcMessage, {&output_dataset_IssueReturnDataSet}) NO-ERROR.

My questions are:

  1. What does the argument "?" means in the method call? What should be the equivalent C# code for it?
  2. What does {&input_dataset_SelectedJobAsmblDataSet} mean in the code? Is it some kind of reference? How should this be coded in C#?
  3. I assume {&output_dataset_IssueReturnDataSet} is the output variable, and hence in C#, I'm assigning values to it like: Erp.Tablesets.IssueReturnTableset output_dataset_IssueReturnDataSet = ...

My code so far has an error for "?", which is suppose to be a GUID:

Erp.Tablesets.IssueReturnTableset output_dataset_IssueReturnDataSet = hIssueReturn.GetNewJobAsmblMultiple(tranType, "?", callProcess, ref output_dataset_SelectedJobAsmblDataSet, out pcMessage);

Solution

  • "?" is a string literal with the text value of ?

    It's different from ? (no quotes) which would be the equivalent to the null value.

    {&input_dataset_SelectedPartDataSet} refers to an Include file parameter or an &SCOPED-DEFINE or &GLOBAL-DEFINE definition somewhere else. It's a preprocessor variable.
